I went to upload my images into Lightroom and found they all stored on my desktop . If I move them into the file where all my other images are they are no longer readable/ no longer recoverable in Lightroom. I have never had this problem before having used Lightroom for 3 years.
The one thing I thought it could have something to do with is they have dropped into Lightroom as for example......untitled - 74.dng
I can see that my other images that have correctly saved in Lightroom room save as for example.......IMG_3217.dng
The last number for my uploads that did work correcly was IMG_8960.dng. I thought if it was close to 10000 then it may have clocked and gone back to zero but this doesn't seem to be the case.
